\section{Plain Text}

 Type your text in free-format; lines can be as long
 or as short
 as you wish.
 You can indent         or space out
 your input
 text in
 any way you like to highlight the structure
 of your manuscript and make it easier to edit.
 LaTeX fills lines and adjusts spacing between words to produce an
 aesthetically pleasing result.
  
 Completely blank lines in the input file break your text into
 paragraphs.
 To change the font for a single character, word, or set of words,
 enclose the word and the font changing command within braces,
 {\em like this}.
 A font changing command not enclosed in braces, like the change to \bf
 bold here, keeps that change in effect until the end of the document or
 until countermanded by another font switch, like this change back to
 \rm roman.
 

\section{Displayed Text}

 Use the ``quote'' and  ``quotation'' environments for typesetting quoted
 material or any other text that should be slightly indented and set off
 from the normal text.
 \begin{quotation}
 The quote and quotation environments are similar, but use different
 settings for paragraph indentation and spacing.
  
 \em When in doubt, consult the manual.
 \end{quotation}
  
 So far, I have demonstrated titles, paragraphs, font changes, and
 section headings.
 Now, I am going to show lists and tables.
 \begin{enumerate}
 \item
 The ``enumerate'' environment numbers the list elements, like this.
  
 Items in a list can contain multiple paragraphs.
 These paragraphs are appropriately spaced and indented according to their
 position in the list.
 \begin{itemize}
 \item The ``itemize'' environment sets off list items with ``bullets'',
 like this.  Finally, the ``description'' environment lets you put your own
 \begin{description}
 \item[A] label on each item, like this ``A''.
 \item[If the label is long,] the first line of the item text will
 be spaced over to the right as needed.
 \end{description}
 \item Of course, lists can be nested, each type up to at least four levels.
 One type of list can be nested within another type.
 \begin{itemize}
 \item Nested lists of the same type will change style of numbering
 or ``bullets'' as needed.
 \end{itemize}
 \end{itemize}
 \item Don't forget to close off all list environments with the
 appropriate \verb+\end{...}+ command.
 Indenting \verb+\begin{...}+, \verb+\item+, and \verb+\end{...}+
 commands in the input document according to their nesting level can help
 clarify the structure.
 \end{enumerate}
  
 Here is a very simple table showing data lined up in columns.
 Notice that I include the table in a ``center'' environment to display
 it properly.
 The title is created simply as another paragraph in the center environment,
 rather than as part of the table itself.
 \begin{center}
 Numbers of Computers on Earth Sciences Network, By Type.
  
 \begin{tabular}{lr}
 Macintosh&175\\
 DOS/Windows PC&60\\
 UNIX Workstation or server&110\\
 \end{tabular}
 \end{center}
  
 Here is a more complicated table that has been boxed up, with a multi-column
 header and paragraph entries set in one of the columns.
 \begin{center}
 \begin{tabular}{|l|c|p{3.5in}|}
 \hline
 \multicolumn{3}{|c|}{Places to Go Backpacking}\\ \hline
 Name&Driving Time&Notes\\
 &(hours)&\\ \hline
 Big Basin&1.5&Very nice overnight to Berry Creek Falls from
 either Headquarters or ocean side.\\ \hline
 Sunol&1&Technicolor green in the spring.  Watch out for the cows.\\ \hline
 Henry Coe&1.5&Large wilderness nearby suitable for multi-day treks.\\ \hline
 \end{tabular}
 \end{center}
 

\section{Mathematical Equations}

 Simple equations, like $x^y$ or $x_n = \sqrt{a + b}$ can be typeset right
 in the text line by enclosing them in a pair of single dollar sign symbols.
 Don't forget that if you want a real dollar sign in your text, like \$2000,
 you have to use the \verb+\$+ command.
  
 A more complicated equation should be typeset in {\em displayed math\/} mode,
 like this:
 \[
 z \left( 1 \ +\  \sqrt{\omega_{i+1} + \zeta -\frac{x+1}{\Theta +1} y + 1}
 \ \right)
 \ \ \ =\ \ \  1
 \]
 The ``equation'' environment displays your equations, and automatically
 numbers them consecutively within your document, like this:
 \begin{equation}
 \left[
 {\bf X} + {\rm a} \ \geq\
 \underline{\hat a} \sum_i^N \lim_{x \rightarrow k} \delta C
 \right]
 \end{equation}
